The census and other periodic surveys were also responsible for the fluctuations in the number of personnel employed. The number of filled posts decreased by 888 in 2012/13 as the contract posts created for Census 2011 enumerators fell away and the focus shifted to the processing and disseminating of the results. The number of permanent personnel employed is expected to increase over the medium term as part of an effort to reduce the number of consultants and contract workers used for fieldwork.
